Central neurocytoma (CNC), first described by Hassoun et al in 1982, is a rare neuronal tumor of the central nervous system, accounting for 0.25% to 0.5% of all central nervous system tumors. To our knowledge, there are only 5 published articles reporting the magnetic resonance spectroscopy (MRS) findings of neurocytomas. The 3-T proton MRS findings of 3(More)
PURPOSE To assess the use of the dual-energy computed tomographic (CT) virtual noncalcium technique in the evaluation of bone marrow edema in vertebral compression fractures. MATERIALS AND METHODS This prospective study was approved by the institutional review board; informed consent was obtained from all patients. Sixty-three consecutive patients with(More)
A 26-year-old woman presented with symptoms of bowel obstruction. An emergent computed tomography (CT) scan was performed which showed ileoileal intussusceptions due to a fatty nodule. Exploratory laparotomy and removal of the involved small bowel was performed. The pathology showed the leading point of the intussusception to be ectopic pancreas with(More)
OBJECTIVE Cerebellar hemorrhage remote from the site of surgery may complicate neurosurgical procedure. The exact pathophysiology of this type of hemorrhage is poorly understood. We retrospectively compared 16 patients who had remote cerebellar hemorrhage (RCH) with a case-matched control cohort, to determine the significance of perisurgical and surgical(More)
The aim of this study is to evaluate the anatomical details of the inner ear and middle ear, using multidetector row CT. Temporal bone CT scans were obtained using 16-detector row CT scanner (Lightspeed 16, General Electric Medical Systems, Milwaukee, WI) in 30 patients with dizziness, vertigo, or hearing loss. The three-dimensional (3D) images were(More)
PURPOSE This meta-analysis examined roles of several metabolites in differentiating recurrent tumor from necrosis in patients with brain tumors using MR perfusion and spectroscopy. METHODS Medline, Cochrane, EMBASE, and Google Scholar were searched for studies using perfusion MRI and/or MR spectroscopy published up to March 4, 2015 which differentiated(More)
A 50-year-old man presented with a middle and posterior mediastinal mass on chest radiograph and computed tomography. Surgical exploration revealed a large dumbbell-shaped lipomatous lesion. Histologic examination confirmed this to be a fibrolipoma. This is the first reported case of fibrolipoma in the mediastinum but outside of the esophagus.
A 51-year-old woman presented to neurosurgery clinic with progressive dropped right eyelid accompanied with blurred vision for 1 month. Neurological examination revealed anisocoria (R/L: 5 mm/3 mm), diminished right light reflex, and complete extraocular paresis, findings suggesting complete oculomotor nerve palsy. MRI showed enhancement of enlarged(More)
Mature teratomas are common neoplasms in the anterior mediastinum. However, a primary carcinoid tumor occurring in a mature teratoma is extremely rare. To our knowledge, there are only 2 published articles in the literature to date reporting a mature cystic teratoma of the mediastinum containing a carcinoid. We herein report another case of primary(More)
